Fix manual scrolling issue on Firefox/Windows (#12648)
Fixes #12607 `will-change: transform` apparently makes manual scrolling impossible on Firefox/Windows. While this should probably be considered a Firefox bug, `will-change: transform` seem like a very aggressive performance hint that may possibly make the browser consume more resources than needed, especially in multiple-column mode. This was originally added to improve scrolling performances on mobile, but I think this isn't necessary anymore, because of the two following reasons: - `contain: paint` (which is implied by `contain: strict`, which we apply whenever the browser supports grids) should have similar effects - in single-column mode, the scrolling container is the root element, which I believe is optimized in at least Chromium Keep in mind that I have not been able to make in-depth benchmarks, and especially not been able to try on mobile, so performances should probably be investigated further…gh/stable
